2 Claims. (Cl. 133-4) The invention relates to coin dispensing machines such as. com changers. 7

The main object of the invention is to provide means for preventing unauthorized operation of the machine and protect the machine against theft. More particularly, the coin magazine is provided with a cover which is normally locked and can only be unlocked by key controlled mechanism, and key controlled means is provided for preventing actuation of the coin ejectors except by an authorized operator.

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

Fig. 12 is a front elevation view of parts shown in Figs. 9 and 10 looking in the direction of the line 12-12.

For the purpose of illustrating the invention I have shown it applied to the modified form of coin changer shown in Figs. 10 to of my prior U.S. Patent No. 2,675,006, dated April 13, 1954, with modifications hereinafter described.

Referring to Fig. 1, the machine includes a metal hous ing 9 having a coin tray or magazine 10 suitably removably mounted at its back end portion, said tray having three penny compartments, one nickel compartment, two dime compartments, one quarter compartment, and one half dollar compartment. There is an ejector mechanism for removing a coin or coins from each compartment. Each of the ejector mechanisms includes an ejector finger 11 pivotally mounted intermediate its ends at 12 on the upper end of a lever 13 pivotally supported intermediate its ends on a shaft 14 mounted in the sides of the machine frame. Each lever 13 is operatively connected by a pusher bar or link 15 with a bell crank rocker lever 16: pivoted on a supporting shaft 17 and adapted to be engaged by one or more actuating fingers 18 formed integral with or secured to a change key 19.

As in the aforementioned patent, certain of the ejector mechanisms, to wit: the half dollar, the twenty-five, and the two ten cent ejector mechanisms, are adapted to be incapacitated by throw out members 20, 21, and 22. A bell crank lever is operatively connected to each of the throw out members and its operating bar or link, and each of these levers is pivotally mounted on a hollow spacer sleeve 23 mounted on the shaft 14. The throw out member 20 is guided at its top by a pin 24' working in a slot thereof, and it is pivotally connected at its end by a pin 25 to an upstanding ear on one arm of a bell crank lever 26 whose other arm is pivotally connected at its lower end by a pin 27 to the end of a pull. bar 28. The throw out member 21 is guided at its top in the same way as the member 20 and is pivotally connected at its lower end by a pin 29 to an upstanding ear on one arm of a bell crank lever 30 whose other arm is pivotally connected by a pin 31 to the end of a pull bar 32. The lever 30 has a projection 30a that extends over an arm of lever 26 so that operation of the pull bar 32 will. also operate the lever 26 so that both the fifty cent andtwentyfive cent ejectors are rendered inoperative. The; throw out member 22 is guided like the others above described and is pivotally connected at itslower end by a pin 33 to an upstanding ear on one arm of a bell crank lever 34 whose other arm is pivotally connected by apin 35 t0 the, end of a pull bar or link 36. Lever 34 has a pro;

- jection 34a that, extends over an arm of lever 3,0. so. that operation of pull bar 36' will' also operate the levers 30 and 26 so that both dime ejectors, the fifty cent, and twenty-five cent ejectors are rendered inoperative. The pull bars above mentioned are operated by special keys as explained in the patent.

In the present case a throw out member 37 guided by pins 38 Working in slots in said bar is mounted to engage over the ejector for the nickel compartment and the ejectors for the three penny compartments, said bar having arms pivotally connected by pins 39 to a lever 40 pivoted on the supporting shaft 14. Lever 40 has an extension 40a that extends over an arm of lever 34 so that when lever 40 is operated, all the throw out members 20, 21, 22, and 37 will be operated, and thus all the ejector mechanisms will be rendered inoperative. Lever 40 is adapted to be engaged by a rod 41 extending transversely of the machine and carried by lever arms 42 and 43 pivotally mounted on the shaft 14. The lever arm 42 has an extension carrying a pin 44 that engages cam surfaces 45 and 46 of a cam member C that is mounted on a key controlled shaft 47 of a lock L which may be turned by the key K. The cam member C is normally urged by a spring 48 to a position in which the pin 44 rides on the cam surface 45 in which position the rod 41 permits the ejector fingers 11 to function in their normal manner to eject coins from the coin compartments, this position being shown in Fig. 4. When, however, on the insertion of the key K the cam member C is turned clockwise as viewed in Fig. 6 to the position shown in Fig. 5, the pin 44 rides on the high part of the cam or the cam surface 46 and acts to depress the rod 44 which swings the lever 40 so as to move the throw out member 37 downwardly to move its associated ejector fingers to an inoperative position and also through the extensions or projections 40a, 34a, and 3012 move the other throw out members 20, 21, and 22 to move their associated ejector fingers to an inoperative position.

Thus the movement of the key controlled cam C acts to move all of the ejectors to an inoperative position and on the removal of the key K the ejectors are locked against actuation by any of the keys 19 so that no coins can be dispensed from the machine.

To further protect the machine, a cover 51 carries a shaft 52 that is pivotally mounted on standards 53 at the rear of the machine, this cover adapted to be swung down over the coin tray or magazine 10 to cover the otherwise open compartments. The cover 51 is secured in its covering position by a pivoted latch 54 enclosed in the machine and engageable in a locking recess 55 in one side of the cover and normally urged to a latched position by a torsion spring 56. The latch is suitably pivotally supported at 57 on the machine frame and has a depending finger 58 that may be engaged by a cam 59 on the side of the cam member C when said member is rotated anticlockwise to the positions shown in Figs. 4 and 7. As indicated in Fig. 8, the lock has three positions, to wit: cover unlocked, operating, and locked.

In the operating position, the cam 59 is free of finger 58, and the pin 44 is riding on the cam surface 45 with the cam in the position shown in Fig. 1 so that the cover is locked and the ejectors are functioning in their normal manner and the key is still in the lock.

In the locked position, the cam C is in the position shown in Fig. so that the ejectors are locked out and the cover is locked since the cam 59 is free of the finger 58 and the key is removed.

In the cover unlocked position, the key is in the lock.

Instead of the cover structure shown in Figs. 1, 2, and 8, I may use the cover 60 shown in Figs. 9 to 12. The cover 60 is hingedly connected at one side by a hinge pin 61 to a hinge bracket 62 secured by screws 62a to the frame of the machine. The other side of the cover has an extension 63 that is provided with a locking notch 64 similar to the notch 55 to receive the latch 54. The cover may have an opening 65 covered with Plexiglas 66 or other suitable transparent material. A rubber bumper 67 may engage the cover in its open position.

I desire it to be understood that this invention is not to be limited to any particular form or'arrangement of parts except in so far as such limitations are included in the appended claims.

What I claim as my invention is:

1. In a coin dispensing machine having a coin magazine provided with coin compartments and a coin ejector mechanism for each compartment, a movable cover for said magazine, means for locking said cover in its covering position, means for incapacitating all of said ejector mechanisms, and key controlled means for permitting movement of said ejector incapacitating means to an inoperative position while the cover is locked, said keycontrolled means also operable to release said cover locking means.

2. In a coin dispensing machine having a coin magazine provided with coin compartments and coin ejector mechanism for each compartment, a movable cover for said magazine, a movable cover latch to hold said cover in its closed position enclosed in the machine, means for incapacitating all of said ejector mechanisms, and a key controlled rotary cam member within said machine and operable from the exterior thereof adapted in one position to release said cover latch and in another position to permit movement of said ejector incapacitating means into an inoperative position while the cover is locked.
